This chapter gives an overview of a Linux system. First, the major
services provided by the operating system are described. Then,
the programs that implement these services are described with a
considerable lack of detail. The
purpose of this chapter is to give an understanding of the
system as a whole, so that each part is described in detail elsewhere.
